I'm struggling to understand what is being said in this line. To provide some context the person was discussing with a girl about his muscles and let her touch them. She then asked if he wanted to touch hers, and he declined (because of his conscience and the fact that she is a naïve sheltered girl).










In the bolded line I am unsure what he saying.

頭をよぎる is used to say that something crossed one's mind. In this case 太ももを鍛えたなんたらいうシナリオ.

太ももを鍛える simply means to work out / train one's legs.

What is confusing me is what なんたらいうシナリオ means and who 太ももを鍛えた is referring to.

  • Isn't there と after なんたら? Isn't it 太ももを鍛えたなんたらいうシナリオ?

  • @naruto not in the text, but it would not surprise me if it is a mistake

This sentence has なんたら, a placeholder similar to "you-know-what", "blah blah" or "whatchamacallit". See: The phrase うんやらかんやら? and What does なんたらという mean?

太ももを鍛えた modifies なんたら as a relative clause. As a whole, this appears to be a reference to a certain episode where someone worked out one's legs. This person used なんたら because he expected the reader could understand what he means only by saying 太ももを鍛えた. See this for a similar example.

However, I am not aware of any well-known episode, title or cliche related to 太ももを鍛えた, and a quick google search gave nothing. Maybe this is a reference to some little-known net meme, or an episode understood only by the readers of this title.

(The sentence usually has to be 太ももを鍛えたなんたらいうシナリオ. It's probably a typo, but this と is occasionally omitted in casual speech or in some dialects.)
